SPECIFICATION forming part of Letters Patent No. 426322, dated April 22, 1890. Application filed July 21, 1887. Serial No. 244331. (Speoimens To all whom it may conccrn: u

Be it known that I, HENRY PU LSTER, of the city and county of Philadelphia, and State of Pennsylvania have invented an Improvement in Knit Fabrics, of which the following is a specification.

My invention has reference to knit fabrics; and it consists in certain mprovements, all of which are fully set forth in the following specifcation and shown in the accompanying drawings, which form part thereof.

The object of my invention is to produce a knit fabric in such a manner that it shall ,have a perfect seersucker appearance-that is to say, it shall be forned of str'ipes or vertical bars of the same or different color effects, and some of the bars shallbe perfectly smootl, while other of the bars or stripes shall be crinkled or full to give an appearance to the fabric similar to what is found in seersucker goods woven upon an ordinary loom. This is, as far as I am aware, entirely novel, and therefore I do not limit myself to any particular design or minute detail as to how it may be accomplished, as a knitted fabric embodying such a feature is a new article of manufacture.

In carrying out my invention I proceed to knit the fabric in the ordinary way well known to those skilled in the use of knitting-machines for making striped or figured fabrics, and the stripes are produced by interlooping with certain of the loops of the plain portion a series of'loops formed of a different thread or threads. The vertical stripe or bar soformed is composed of twice as many loops in its length as are found in the plain portions or plain bars, and is composed of alternate rows of loops from the thread composing the loops of the plain bars and the additional thread found only in its own loops. The increase in the number of these loops at certain parts of the fabric is what produces the fullness or seersucker appearance. It is evident that if in a given length of the fabric we have a series of vertical rows of loops composed of, say, 'one hundred loops, and interspersed with such vertical rows ot' loops we have rows composed of two hundred loops in the same space, the bar or portion of the fabric composed of the last-mentioned loops must be crinkled, but at the same time brought within the desired length, and hence will impart the desired seersuckerappearance to the fabric. During theformation of such fabric there will be a tendency to produce floats upon the back of the fabric between consecutive crinkled bars; but to avoid these floats I cause them to be tied into the smooth part of the fabric at its back and at one or more places in each float, so thatwhn the completed fabrio is examined it will be found devoid of loose floats upon the back, and hence there is no liability of the parts fornerly found as fioats catching upon the fingers, or in any other way being pulled or dragged so as to injure the appearance of the face of the fabric. It is to be understood that I do not confine myself to any particular apparatus for producing the fabric. In fact, it may be made by hand so far as my invention is concerned, the generic feature being the production of a knitted fabric with one or more full or crinkled bars to give a seersucker appearance.

In the drawings, Figure lis an elevation of a piece of fabric embodying my invention,

looking from the back; and Fig. 2 is a front elevation of a small portion of same.

A is the ordinary knitted body portion, or

that forming the smooth part of the fabric, the loops being connected as usual by the parallel horizontal thread parts a.

C represents vertical bars formed of a series of loops D and l-I arranged alternately. The loops H are forned of the threads which make up the smooth loopsAof the fabric, and the loops D are formed of additional threads, which form the part O, and pass to the right and left, as at E, back of a vertical line of the body-loops A, then in front of a horizontal thread part a of the loops A, and then back of another vertical line of loops, as at F, then down in front of another thread a, then back of another Vertical line of loops A, and next to a second line of loops C, forming another bar. From this construction it is seen that more places.

IOO

three vertical lines of loops; but it is evident that it may consist of one or more vertical lines of loops, as desired, and in place of the floats being tied in by two threads a they may be tied in by a series of threads, according as to the number of vertical lines of loops A used between bars O.

If the threads forming the loops D of the stripe C be of the same color as the thread of the body part forming the loops H in the stripe C, then the color effect will be the same in stripes C as in the body parts A; but if said threads are of different colors then a mottled or different color effect will be produced in stripes O from that of the bodystripes A.

An examination of Fig. l will disclose the fact that the bars C are composed of twice as many loops in their vertical length as the bars A, and hence the desired fullness is obtained.

To, make the fabric with f uliness in the bars C, the bars A must have their loops under greater tension than the loops of the bars O, for in the latter case there are twice as many loops in the same length of the fabric.

While I have shown the bars A and C of the same width, it is evident that they may just as well be of different widths, and in practice the manufacturer would 'so make them to a large eXtent to suit the fancy.

lt is evident that the fioat parts E F E might be roughened or carded in the usual manner to make a pile back, if. so desiredf I do not limit myself to the mere details of Construction here shown, as the same effect might readily be produced by one skilled in the art in a number of different ways without in the least departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A knit fc bric formed of a series of horizontal rows of loops, and in which the loops in the same row are formed of the same thread, and having two or more vertical bars of loops, the alternate bars being formed, respectively,

- of an unequal number of loops connected lengthwise with the fabric, so as to make alternate bars full and give a seersucker appearance.

2. A knit fabric having two or more alternate vertical bars of loops, the loops of alternate bars being formed from two separate threads knitted into rows of loops arranged alternately, and the loops of the other bars being formed from one only of said threads, and in which thelateral loops in any horizontal line or row of loops are formed of the same thread. 4

3. A knit fabric having a' body portion formed of loops knit in the ordinary way, with the loops in the same horizontal line formed of the same thread and provided with vertical stripes formed of one or more threads knit into loops which are interlooped with the body-loops at the place where the stripe is formed, and in which the same thread connects two or -more stripes at the back of the fabric and is tied into the body of the fabric between the stripes, whereby a fabric having a seersucker appearance is forned without loose fioats between the stripes.

4. A knit fabric formed of a body part knitted in. the usual way and provided at intervals apart with 'additional loops interlooped with alternate rows of the body-loops to form stripes or bars, whereby such latter parts of the fabric have many more loops in their vertical length than the plain body portions, and such stripes will be made up of alternate transverse rows of body-loops and additional loops.

5. A knit fabric having a portion of its surface made full or loose, said portion being composed of the body-loops and additional connecting-loops existing only at such full or loose part and arranged in a vertical line or length of the fabric alternately with the bodyloops.

6. A knit fabric having alternate vertical bars or stripes formed, respectively, of different numbers of loops in their vertical length, the loops of adjacent stripes or bars being held in the direction ot' their length under different degrees of tension, and thereby producing a fullness in alternate bars orstripes with the loops in the same horizontal line formed of the same thread.

In testimony of which invention I hereunto set my hand. 4
